Rotary Paddle Level Switch
Model No: KCPL-RP Series
Rotary Paddle Level Switches are designed for reliable high- and low-level detection of powders, granules and bulk solids in silos, hoppers, bins and process vessels.
A motor-driven paddle rotates freely when no material is present. When the material reaches the paddle, its rotation is restricted, activating the switching mechanism and providing a level indication or control signal. The motor is automatically protected during the covered condition.
The rugged shaft-sealing arrangement helps prevent dust ingress, while multiple mounting, insertion-length and paddle configurations make the switch suitable for a wide range of bulk-solid applications.
